BYK ANTI-TERRA-250 is a high-performance, acidic polymeric alkylol ammonium salt wetting and dispersing additive designed for waterborne basecoats and filler slurries. It stabilizes pigments and fillers by controlling flocculation, forming three-dimensional "bridges" between particles to prevent flooding, floating, and settling. It is compatible with inorganic and organic pigments and enhances thixotropy while maintaining long-term stability in waterborne formulations.
Controlled Flocculation - Creates particle bridges to prevent pigment separation and settling
Universal Compatibility - Works with inorganic fillers (e.g., CaCO₃) and organic pigments
Thixotropy Enhancement - Improves anti-sagging properties without excessive viscosity buildup
Eco-Friendly - Water-based formulation with 70% active content, VOC-free
Process Stability - Maintains performance across pH variations (4-10)
Architectural Coatings - Exterior aqueous primers with anti-settling requirements
Industrial Fillers - High-load slurries for cement/fiber products (e.g., fiberboard coatings)
Wood Coatings - Water-based systems needing controlled pigment distribution
Printing Inks - Flexographic inks for packaging films requiring color consistency
Anti-Corrosive Primers - Direct-to-metal coatings with sedimentation resistance
